The nuclear-physics landscape has been redesigned as a sequence of effective field
theories (EFTs) connected to the standard model through symmetries and lattice simulations …

In this review, we present the current state of the art of our understanding of the spectrum of
excited strongly interacting particles and discuss methods that allow for a systematic and …

The physical interpretation of lattice QCD simulations, performed in a small volume, requires
an extrapolation to the infinite volume. A method is proposed to perform such an …

Most strong-interaction resonances have decay channels involving three or more particles,
including many of the recently discovered X, Y, and Z resonances. In order to study such …

A bstract The nature of the three narrow hidden-charm pentaquark P c states, ie, P c (4312),
P c (4440) and P c (4457), is under intense discussion since their discovery from the …

We investigate the relativistic scattering of three identical scalar bosons interacting via pair-
wise interactions. Extending techniques from the nonrelativistic three-body scattering theory …

We use the leading-order contact interactions and one-pion-exchange potentials to
investigate the newly observed double-charm state T cc+. We employ the complex scaling …

A bstract We derive the three-body quantization condition in a finite volume using an
effective field theory in the particle-dimer picture. Moreover, we consider the extraction of …

The last two decades have witnessed the discovery of a myriad of new and unexpected
hadrons. The future holds more surprises for us, thanks to new-generation experiments …

Many excited states in the hadron spectrum have large branching ratios to three-hadron final
states. Understanding such particles from first principles QCD requires input from lattice …
